Product Summary

The CDP1805ACE is a kind of functional and performance enhancement of the CDP1802 CMOS 8-bit register- oriented microprocessor series and is designed for use in general-purpose applications. The CDP1805ACE hardware enhancements include a 64- byte RAM and an 8-bit presettable down counter. The Counter/Timer which generates an internal interrupt request, can be programmed for use in timebase, event-counting, and pulse-duration measurement applications. The Counter/Timer underflow output can also be directed to the Q output terminal.
